Abstract |
: |
Multivariate statistical techniques, such as cluster analysis and principal component analysis were performed on 22 well-representative groundwater samples gathered from different tributaries of Wadi Ranyah, Western Provence, Saudi Arabia. The collected samples were analyzed for a total of 21 water quality descriptors (variables) including major and trace elements. From traditional Durov diagram water classification, the water quality is Calcium-Bicarbonate type. In addition, saturation indices (SI) were calculated for Anhydrite, Gypsum and Halite and the results show that the water is under-saturation state. R-mode cluster analysis resulted in two distinctive sources controlling water chemistry: groundwater-rock interaction, agriculture and anthropogenic sources. The first three principle components explained 70% of the total data variability. First factor reveals strong associations between Ca2+, Mg+, Na+, HCO3¬-, SO¬¬42-, pH , TH and conductivity and trace elements as PO¬¬43-¬ and SiO2. The second factor represents the high loading of NO3- and Mn+ as the input of soil water. The third factor reveals high loading of Chloride (Cl-) which may be due to the flushing of evaporate minerals with recent rainfall recharge. Plots of samples of F1 versus F2 show approximately one group with good separation of outlier samples, where F1 versus F3 allowed good separation of two groups. |
